Abstract

A guide rail (10) exhibits running surfaces (19), which are separated from one another by a longitudinal slot (20), and a carrying part (9) which is supported on said running surfaces, is guided displaceably and non-rotatably in the guide rail and on which there is fastened, in a suspended manner, a closure element, preferably a doorleaf (7) of a sliding folding door. In order to be able to connect, in a simple and rapid manner, the closure element, borne by the carrying part, to the guide rail, the carrying part (9) exhibits an elongate carriage part (14) which is guided in the guide rail and is of a width which corresponds to the longitudinal slot of the guide rail. In the carrying part (9) there is mounted rotatably, but axially non-displaceably, in a bore which is at right angles to the guide rail (10), a bolt (27) which bears, in the region of the carriage part (14), a hammer-head-like head (26) whose width is smaller, and whose length is greater, than the width of the longitudinal slot (20). The bolt (27) can be locked to the carrying part (9) in a position in which the head (26) is supported on the running surfaces (19). <IMAGE>

2. Description of the Related Art German Patent Publication No. 8400107U discloses a folding sliding door, which has an upper guide rail with symmetrically mounted mounting heads, in which a roller load is applied. The support member moves and a hinge arm connecting the outer door to the roller support member can be mounted on the roller load support member such that the arm can be moved left and right as desired. The fitting of this known folding sliding door is a complicated task, since the hinge arms, which have to be connected with the roller load bearing members, are already held on guide rails and there is no proper access to such parts Because. In the case of the known guide rail according to German Patent Publication 9300918U of the type mentioned first, a simple mating is possible,
The load-bearing member is provided with a locking device, which has a detent lever, and the wing connected with the pin is connected to the detent lever by receiving-receiving insertion of the connecting portion having the pin. Because you can do it. To create a receiving connection with the detent lever, the pin is provided with a head that can be stopped by the lever. Although this known design allows quick assembly in the receiving action by simple insertion of the pin into the locking device, removal of the locking device is difficult, and furthermore, the load-bearing member and the fixed The connecting part that can be made has a complicated contour to allow a releasable receiving action.

SUMMARY OF THE INVENTION Accordingly, one of the objects of the present invention is, on the one hand,
With a low-cost structure configured as described above, on the other hand, the closing element supported by the load-bearing member can be simplified,
It is another object of the present invention to provide a guide rail of the type described above, which can be connected quickly. According to the invention, the load-bearing member moves in the guide rail and has an elongated carriage part having a width corresponding to the longitudinal slit, the pins being rotatable but fixed in the axial direction. It is supported by the load support member with a hole perpendicular to the guide rail,
The pin has a T-shaped head adjacent to the carriage portion, the width of the T-shaped head is smaller than the width of the longitudinal slit, the length of the T-shaped head is larger than the width of the longitudinal slit, Since the pin is locked with the T-shaped head in contact with the moving surface, the above object can be achieved. The load bearing member according to the invention has a simple profile, because the load bearing member
In essence, it has an elongated carriage portion that moves in a guide rail, and the guide rail has a T-shaped or rotatably mounted guide for guiding in the guide rail, or
A hammer-shaped head is provided, and the limb of the head constitutes a sliding shoe that moves on the guide rail when turned in the lateral direction. If the limbs of the T-shaped head are arranged so as to be oriented in the longitudinal direction of the carriage part, these limbs then do not extend beyond the width of the carriage part, and the fitting and connection of the load bearing member with the guide rail Therefore, the carriage portion can be inserted into the guide rail through the longitudinal slit. Once such insertion has been made, all that is required is to rotate the pin 90 ° using simple actuation means to lock the carriage portion to the guide rail, and the limb of the T-shaped head is supported as a sliding shoe. Will be.
Thus, the load-bearing member according to the invention can be connected to the closing element even before final assembly, and then requires the insertion and locking of the carriage part of the load-bearing member in the guide rail in place. It just does.

According to yet another aspect of the present invention, a base portion extending transversely to the carriage portion of the load supporting member is connected to the carriage portion, and the hinge arm of the furniture hinge is moved transversely to the guide rail. Orientation can be attached to the base part. This design according to the invention provides a simple and quick fitting of the retaining device to the outer door of the folding sliding door. The support plate can be attached to the base part, and the hinge arm is
It is guided laterally on the support plate using a self-locking mounting device. In this regard, the guides protrude from the angled, aligned holes in the limb of the support plate, through which pins penetrate and which pins are fixed to the angled limb of the hinge arm. Is done. Furthermore, the self-locking mounting device has an eccentric device, the eccentric of which is located in a slot in the flange portion of the hinge arm.
A support plate is mounted on the base portion so as to be able to slide longitudinally and can be secured by mounting screws passing through the keyhole slots. In this way, a simple adjustment in the longitudinal direction of the hinge arm is possible. Another advantageous feature of the invention is that the mounting screw is at the same time a set screw of a pin with a T-shaped head. If the limb of the T-shaped head places the pin in a position where it rests as a sliding shoe on the moving surface of the guide rail, the pin is locked in this position by further tightening of the mounting screw. Become.

According to a further advantageous embodiment, the pin comprises an angled working part, said part being one of the base parts in a position where the T-shaped head is transverse to the longitudinal slit. On Frank. With this mounting,
The T-shaped head is then turned into its locked state,
It is simply and quickly possible to release the shaped head again.
According to a preferred embodiment, the stop and mounting screws are arranged on the side of the base part facing the wall of the adjacent body in the closed position of the folding sliding door. In this way,
When the folding door is opened, it can be easily fitted and adjusted. According to another possible aspect of the invention, the carriage part has bifurcated limbs at both ends, the bifurcated limbs carry pins supporting the rollers, the rollers being part of a part of the guide rail defining a longitudinal slit. It is located between the edges. These rollers enhance the movement of the carriage part in the guide rail. According to a particularly preferred form of the invention, the carriage part is made bilaterally about a vertical transverse plane,
The load support member is bilaterally symmetrical with respect to a vertical intermediate longitudinal plane. This design provides a simple way to mount the left or right door as required, depending on whether the door is hinged to the body wall.

Advantageously, the T-shaped head is supported in a central window-like opening in the carriage part. The carriage portion connected to the base portion in an integral manner may have plastic injection molded components. Further, the T-shaped head and the rollers may be made of synthetic resin injection molded components.
Next, an operation example of the present invention will be described in more detail with reference to the drawings.
